  2. OP AMP LM324 high supply current

    i am working with LM324 quad op amp , making a normal inverting amplifier with DC offset. the amplifier take a saturated signal come from another amplifier and try to add the DC offset and the gain is 1. the problem is this opamp take a lot of supply currents ( 35 mA) though it must be only 1.3 mA. Any one could help me to know what is the source of this high current ? :blank:

  5. Flexible notation for inputting literal numbers in Tachyon

    Forth is very flexible with inputting and outputting numbers in any base, the most common being decimal, hex, and binary. Normally you just set the base you want but sometimes you want to make sure that no matter what the base is set to that a number is recognized correctly. Other times you may want a number to be more recognizable such as 80,000,000 and so on.

    So here's a quick introduction to the way we can specify how literal numbers are handled on input into Tachyon, which makes ...
